River EX-5 Cement Extrusion Technology
An engineering-led extrusion platform under development for large-scale cementitious additive manufacturing and robotic fabrication integration.
Equipment development
A system approach to cement extrusion.
Extrusion reliability depends on the full material-delivery system: feed preparation, pumping, flow control, injection, deposition geometry, motion integration, cleaning, and safe operation. We are developing EX-5 around these interconnected requirements.
Discuss system integrationEngineering capabilities
Designed for the entire material pathway
The following are engineering focus areas, not published performance guarantees.
Accelerator & additive integration
Evaluation of inline dosing and mixing approaches for application-specific formulations.
Robotic & process integration
Interfaces among the printhead, pumping system, controls, and robotic toolpaths.
Material compatibility
System performance depends on solids content, aggregate grading, rheology, and curing behavior.
Maintenance & serviceability
Access for cleaning, wear-component replacement, and repeatable startup/shutdown routines.
Prototype evaluations
Discuss paid technical trials, pilot integration, and collaborative engineering studies.
